10 Claims.

This invention relates to washing apparatus for barrels, kegs and thelike and has for an object the provision of an improved construction andarrangement whereby the interior and exterior of this type of containermay be thoroughly cleaned.

Another object of the invention is the provision of mechanism forautomatically lling a barrel partly full of water before it is deliveredto the brushing apparatus in order that a preliminary soaking andrinsing of the interior may take place during the exterior brushingoperation.

A further object of the invention is the provision of a single structurein which a number of different steps are provided for cleaning theinterior and exterior of `barrels and like containers, with thedifferent parts all coacting with each other to successively perform thevarious cleaning operations and remove the cleaning fluid, so that thebarrel or other container may be automatically fed in at one end anddischarged at the opposite end, thoroughly cleaned.

Another obiect of the invention is the pro- Vision of a machine ofthischaracter, wherein the Various parts are so constructed andarranged, that the machine as a whole is Very compact and requires butvery little floor space for its installation and operation.

A still further object of the invention is the provision of a machine ofthis character that is Very eiiicient in operation, but is relativelycheap to manufacture and will operate continuously for a long time withpractically no maintenance cost.

One embodiment of the invention is illustrated in the accompanyingdrawings wherein Fig. 1 is a side elevation of a barrel washingapparatus embodying my invention; Fig. 2 is a horizontal sectional viewtaken on the line 2 2 of Fig. 1; Fig. 3 is a longitudinal sectional Viewtaken on the line 3 3 of Fig. 2; Fig. 4 is a transverse section throughthe exterior scrubbing mechanism taken on the line 4 4 of Fig. l; Fig. 5is an enlarged detail sectional view through the interior spraying, andbarrel discharge mechanisms taken on f the line 5 5 of Fig. 6; Fig. 6 isa vertical sectional View taken on the line 6 6 of Fig. 5; Fig. '7 is afragmentary plan view of the parts shown at the left hand side of Figs.5 and 6, and Fig. 8 is a vertical sectional view taken on the line 8 8of Fig. 5, the parts having been rotated through 90 from the positionsshown in Figs. 5, 6 and 7.

Referring to the drawings by numerals, l indicates generally anautomatic loading mechanism which receives kegs from an inclined runway2,

'A and delivers them to a filling station 3, where a predeterminedamount of either hot or cold water is put into the keg.

From the lling station, the keg is automatically transferred to ascrubbing mechanism 4, where the exterior of the keg is thoroughlycleaned by rotating it between a set of brushes which engage both theperiphery and the ends of the keg, Water being sprayed thereon while itis in this mechanism. 'I'he rotation of the keg by the scrubbingmechanism agitates the Water placed therein at the iilling station andthoroughly soaks and rinses the interior of the keg.

From the scrubbing mechanism the keg is transferred to a bung locatingmechanism 5 where it is rotated until the bung locater enters the bunghole and holds it (the keg) stationary until it is engaged by a combinedinterior spraying and discharge mechanism 6, which takes the keg fromthe bung locating mechanism 5, and deposits it on a discharge runway l.The keg is held, with the bunghole opening downwardly, in the bunglocating mechanism, for a predetermined length of time before beingengaged by the discharge mechanism, to allow the water placed therein atthe filling station to drain out. While the keg is being transferredfrom the bung locating mechanism to the discharge runway, the interiorthereof is intermittently sprayed with hot or coldwater.

The various transfer mechanisms for transferring the kegs from onestation or mechanism to another are all timed together and are soconstructed and arranged that all the kegs in the machine (after it hasbecome fully loaded) are moved simultaneously from one station, ormechanism to the next.

The scrubbing mechanism 4, bung locating mechanism 5, and combinedinterior spraying and discharge mechanism 6, are all located on a mainbase 8, and the filling station 3 is secured to an auxiliary base 9,which is placed adjacent the main base 8. The loading mechanism I isalso supported from the auxiliary base.

By arranging the various mechanisms in this manner, it is possible toconstruct a machine either with or without the filling station 3,without changing the construction of any of the individual parts. Whenthe lling station 3 is omitted, the loading mechanism I is supportedfrom the main base 8, and delivers kegs from the runway 2, directly tothe scrubbing mechanism 4.

The specific construction and operation of the various stations andmechanisms above referred to will now be described.

The lower end of the inclined loading runway Cil 2 joins a framework l5,in which a pair of keg receiving members I! are pivotally mounted on atransverse shaft l2. Each of the members II has a roller i4 on one end,and has its other end connected to a ccunterweight I3 which extendsbetween said members. A pair of arms I5 are rigidly secured to a shaftIll, and cooperate with the members il to receive a keg from the runway2. These arms are connected together by a tie rod 4.53, and are concavelas indicated at I6. As the arms i5 are moved upwardly by the rotation ofthe shaft il', to deliver a keg to the lling mechanism 3, the weightedends of the members li drop down to allow a keg to roll onto them, fromthe runway 2. Then as the arms I5 are moved downwardly to the positionshown in Figs. 1 and 3, they come into contact with the rollers i4,depress the rear ends of the members II, causing a keg to roll into theconcave parts I6 of the arms I5, and elevate the forward ends of themembers II, thus preventing another keg from rolling onto them until thearms I5 have been again elevated to deliver the keg, just received, tothe filling mechanism.

The `shaft il is journalled in bearings IS carried by the side framesI9, of the filling mechanism 3, which in turn are fastened to theauxiliary base 3.

IThe lling mechanism, generally, comprises the auxiliary base 9, sideframes I9, and two pairs of rollers and 2l which support and rotate akeg in operative relation to a bung locating filling nozzle 22 which isattached to one end of an arm pivoted at 2li to one of the sidel framesof the scrubbing mechanism. The rollers 20 are rigidly secured to ashaft 25, which is rotated through av friction clutch 25, and isjournaled in bearings 2i carried by the side frames I9. The rollers 2lare rotatably mounted on stud shafts 28 carried by brackets 2s, whichare adjustably secured to the side frames i3 as indicated at 33. Theadjustable mounting of the brackets 29 permits the accommodation of themachine for various size kegs. The manner of rotating the shaft 25 willbe explained hereinafter.

As soon as a keg has been placed on the rollers and 2 l, by the loadingmechanism I, the bung locating nozzle 22 is lowered by mechanism to bedescribed hereinafter, until the roller 22a on the lower end thereofcomes into contact with the periphery of the keg. The keg is rotated bythe rollers 25 and shaft 25, until the nozzle 22 drops into the bunghole, it being understood that the nozzle 22 is positioned in line withthe bung hole. A valve 3 l in a water line 32, is supported in closeproximity to the arm 23, and is opened by a weighted arm 33, which isconnected to the arm 23, by a link 34. A flexible hose 35 connects thevalve 3l and the nozzle 22. When the nozzle 22 drops into the bunghole', theV rotation of the keg is stopped and the valve 3l is opened toallow water to flow into the keg through the flexible hose 35 and nozzle22. After a predetermined time, the nozzle 22 is withdrawn from the kegand the valve 3| is closed. The keg has then been more or less lled withwater, as desired, and is ready to be transferred by the transfermechanism 3a to the' scrubbing mechanism 4 which is closely adjacent thefilling mechanism.

The scrubbing mechanism 4 may be any of numerous well known designs. Theone herein illustrated, somewhat diagrammatically, comprises generallytwo pairs of rollers 36 and 37 rigidly secured on rotatable shafts 38and 33, respectively, peripheral brushes 4S, `and end brushes 4l. Theshafts 38 and 35 are journaled in bearings 42, carried by brackets 43extending upwardly from the baseI 8. Side frames 44 are fastened to thebase 8 and brackets 43 and extend upwardly therefrom to support thebrushing mechanism.

Water is sprayed onto the exterior of a keg, while it is in thescrubbing mechanism, by a sprinkler pipe 54, and a pair of spray nozzles65.

The peripheral brushes lil are carried by one end of a lever 45 which ispivotally mounted on a cross shaft 45 extending between the side frames44 near the upper edge thereof. The angular position of these brushes4i! is adjusted and maintained by a link 4l. The brushes drop by gravityonto the kegs, and a counterweight 48 on the other end of the lever 45is used to regulate the force with which they engage the periphery ofthe keg. The limit to which the brushes may fall when the brushingmechanism is empty is regulated by a flexible cable 49, one end of whichis attached to the brushes and the other end wound onto a drum 5B.

The en-d brushes 4I are adjustably secured to arms 5I. A pair of links52 having their lower outer ends pivotally fastened to the arms 5I andtheir inner upper ends pivoted to brackets 53 on the upper outside facesof the side frames 44, swingingly support the arms 5I and brushes 4I insuch a manner that the brushes are always maintained in a horizontalposition. When a keg is in the brushing mechanism, the brushes areallowed to swing by gravity into engagement with the ends of the keg,through opening 44a in the side frames 44; and when a keg is beingdelivered to, or transferred from the brushing mechanism, the brushes 4Iare swung outwardly by a flexible cable, or chain, 54, which has one endfastened at 55 to the links 52 on the near side of the machine as viewedin Figs. l and 2. This cable or chain 54 passes over a pulley 56,rigidly secured to a transverse shaft 5l, then over a pulley 58 rigidlysecured to the shaft 46 and then over an idling pulley 59 and has itsother end attached to an operating lever 60 which is reciprocated at theproper time by mechanism described hereinafter. A pulley 6I is rigidlysecured to the opposite end of the shaft 5l, and has one end of a shortcable or chain 62 connected thereto, the other end thereof beingconnected to the adjacent links 52 at 63. Thus when the cable 54 ismoved, the shaft 5l is rotated and the brushes 4I are swung inwardly oroutwardly simultaneously.

A flexible cable 23EL has one end attached to a pulley (not shown) onthe shaft 46, and the other end secured to the pivoted arm 23, whichcarries the bung locating nozzle 22. In this manner, the nozzle 22 islowered to engage, or is withdrawn from, the bung hole of a keg at thefilling station 3.

After a keg has remained in the brushing mechanism a predeterminedlength of time, the lever 6Fl is operated to withdraw the brushes 4Ioutwardly away from the ends of the keg. From the foregoing it will beapparent that the nozzle 22 will be raised at the same time that thebrushes 4I are withdrawn.

A transfer mechanism 4a similar to the transfer mechanism 3ft is thenoperated to transfer the keg in the scrubbing mechanism to the bunglocating mechanism 5.

The transfer mechanism 3a and loading mechanisrn I, are operatedsimultaneously with transfer mechanism 4e so that as a keg istransferred from the scrubbing mechanism tc the bung locating mechanism,the keg in the filling station will be transferred to the scrubbingmechanism, and a fresh keg will be delivered to the lling station.

The transfer mechanism 3a is rotatably mounted on a transverse shaft 10,and the transfer mechanism de is rotatably secured to the upper end of abracket 1i, extending upwardly from the base 8. .l

Each of these transfer mechanisms 3a and 4a comprises a swinging arm 12having a pair of keg engaging rollers 13 mounted on a short shaftcarried by the free end of the arm 12; and a depending lever 13a pivotedat 14 to the arm 12. The levers 13a can swing freely in acounterclockwise direction but are prevented from swinging in aclockwise direction by stops 15 on the arms 12. A stop 16 prevents themechanism 3a from swinging below the position shown in Fig. 3 and thedownward movement of the mechanism da is limited by the engagement ofthe arm 12 with the bracket 1I.

Directly below the mechanism Ila, a lever 11 carrying a roller 18 on oneend is pivoted to a bracket 13 on the base 8; and directly below themechanism 3a a similar lever 80 having a roller 8| on one end is pivotedto a bracket 82 on the auxiliary base 8. The lever 11 is connected tothe lever 83 by a link 83, and the link 88 is in turn connected, by alink 8d, to the lower end 85 of an operating lever 88, that is fastenedto the shaft I1. The upper end of the operating lever 88 is forked asindicated at 81 and 88. When the shaft I1 is rotated in a clockwisedirection, the levers 11 and 8B are rotated in a counter clockwiseAdirection by the lever and the links 83 and 84, and engage through therollers 18 and 8| `the depending levers 13a of the transfer mechanisms3e and 4e, to rotate the arms 12 in a clockwise direction. Atl the sametime the fork 81 of the lever 86 will engage the tie rod I5a and rotatethe arms I5 upwardly in a clockwise direction. When the rotation of theshaft I1 is reversed, the levers 11, 80 and 86 will be movedback to theposition shown in Fig. 3, allowing the loading mechanism I and thetransfer mechanisms 3a and da to return by gravity to the position shownin this figure. The fork 88 is provided to positively start the downwardmovement of the arms I5, in case they should be moved past dead centeron the upward movement.

The bung locating mechanism 5 consists of a pair of driven rollers 98, apair of idler rollers 9|, and a plunger 92 which is spring pressedupwardly into the bung hole of a keg, after it has been rotated intoalignment with the plunger 92, by the rollers 9|] and 9|.

The rollers Sil are fastened to a shaft 93 that is journaled in bearings94 carried by side frames 95 and 96 secured to the base 8, and isrotated through a friction clutch 91. The rollers 9| are rotatablymounted on stud shafts 98, carried by brackets 99, which are adjustablysecured to the side frames 95 and. 86. This manner of mounting therollers 9|, together with the adjustable mounting of the rollers 2|,permits the machine to be used for washing diiferent size kegs.

The plunger 92 is fastened to a member |83, which is swinginglysupported, in such a manner as to always be in a vertical position, by apair of parallel links IilI which have one of their ends pivoted to themember |38 and their other ends pivotally mounted on transverse supports|02, extending between the frames 95 and 96. A compression spring |83normally urges the member |88 and plunger 92 upwardly.

When a keg is delivered to the bung locating mechanism 5 from thescrubbing mechanism Il, it is supported on the rollers `and 9| and isrotated by the rollers 90 until the bung hole comes into alignment withthe p1unger92. The spring |03 then pushes the plunger 92, which untilthis time has been bearing against the periphery of the keg, into thebunghole and .stops the rotation of the keg. The keg remains in thisposition for the timed interval, which is the same for all the stationsand mechanisms, and the balance of the water remaining in the keg whichwas placed in the keg at the lling station 3, drains out. The keg isthen lifted from the rollers 90 and 3l, by the combined interiorspraying and discharge mechanism 6 and is discharged from the machineonto the discharge runway 1. During the time it is being moved from thebung locating mechanism to the discharge runway, the interior thereof isintermittently sprayed.

`The combined discharge and interior spraying mechanism 6 consistsgenerally of a pair of revoluble saddles for supportingra keg, a nozzlecarried by each saddle and adapted to enter the bung hole of a keg whileit is in the saddle; means for revolving the saddles and means forintermittently admitting water to the nozzles while the saddles arebeing revolved. The revolving mechanism is so constructed as to alwaysmaintain the saddles in an upright position.

The saddles IIB which are formed integrally with body parts |I I, havetheir sides concave, as indicated at II2, and have their front wall andbottom slotted at II3. The concave sides adapt the saddle for use withvarious size kegs, and the slots II3 permit the saddles to pass theplunger 92 and connected parts. Spray nozzles H4 are secured to each ofthe "body parts II I and project upwardly through the slots I I3.Longitudinal bores |I5 connect the interiors of the nozzles with groovesII 8 which surround transverse bores II1 in the body parts III. ShaftsII8 project outwardly from valve bodies IIS into the bores II1. Theshafts I I8 have longitudinal bores |20, and transverse bores I2I whichconnect the interior of the valve bodies IIQ with the grooves IIB.Packing glands II1EL prevent any leakage along the shafts IIB. v

The valve bodies IIS are fastened to opposite ends of an arm |22, whichhas a short shaft |23 formed integral therewith, midway between theshafts I I8 and in parallelism therewith, and projecting outwardly inthe opposite direction to the shafts I I8. The shaft |23 is journalledin a bearing |24 on a bracket |25 fastened to the base 8; and has acentral bore |26 which connects with a passageway |21 which in turnconnects with the interior of the valve bodies I I9, as indicated at|28. A short shaft |29 projects outwardly from the arm |22 in theopposite direction to the shaft |23 and in alignment therewith, and hasa gear |38 keyed thereto.

Each of the body parts III has a second bore I3! spaced from andparallel to the bore II1. Stud shafts |32 secured to opposite ends of anarm |33, are mounted in the bores I3I. A cup shaped member |34 securedto the arm |33, midway between the shafts |32 an-d in parallelismtherewith, extends outwardly therefrom in the same direction as theshafts I 32. The member I 34 surrounds a bearing |35, projectingoutwardly from a gear box I 36, and is secured to a shaft |31 whichextends out from the gear box and is journaled in the bearing |35.` Theother end of the shaft |31 is journaled ,ina vbearing .|138

carried by the cover |36 of the gear box. A gear |40, identical with thegear |36 is keyed to one end of the shaft |31. A gear cage |4| whichencloses the gears |36 and |40, has one en-d rotatably mounted on theshaft |29, and the other rotatably mounted on a circular extension |34eon the cup shaped member |34. An idler gear |42 which meshes with thegears |30 and |40 is rotatably mounted on a stud |43 carried by the gearcage |4| in parallelism with the shafts |29 and |31.

By reference to Figs. 5 and 6, it will be seen that the distance betweenthe center of the shafts |25 and |31 is the same as the distance betweenthe centers of the bores ||1 and |3| in each of the parts The variousparts just describe-d are so constructed and arranged that when they arein the position shown in Fig. 6, the centers of the shafts |26 and |31and the centers of the bores ||1 and |3|, and consequently the shafts I8and |32, are all in the same horizontal plane.

When the shaft |31 is rotated, the arms |22 and |33 will be rotated inunison-the arm |33 being positively driven through the cup shaped member|34 which is keyed to the shaft |31, and the arm 22 being positivelydriven from the shaft |31 through the gears |40, |42 and |30 and theshaft |29. The rotation of the arms |22 and |33 will revolve the saddlesH6, and always maintain them in an upright position as they are beingrevolved.

A Water supply pipe 56 is inserted into the bore |26 in the shaft |23,and is held therein by a packing gland |5| which prevents leakage ofwater around the pipe |56.

Water is supplied to the nozzles |54 from the supply pipe |56 throughtirefbore |26, passage-- way |21, valve bodies H9, bores |25 and |2|,grooves ||6 and passageways ||5.

A valve |52, normally held in closed position by a spring |53, and thepressure of the water, is mounted in each of the valve bodies H9. Thevalves |52 are secured to slidable spiders |54 which have valve stems|55 secured to the opposite ends thereof, and project out through caps|56. When the valves |52 are in closed position, the supply of water tothe nozzles |4 is stopped.

Arms |51 pivoted at |58 to brackets |55 on the caps |55 are positionedover the ends of the valve stems |55, and each has a roller |55 securedto the free end thereof. Arcuate cams |6| each having a notch |62 in itscam face are rotatably mounted on studs |63 carried by the body partsand are positioned in the plane of the rollers |60. Levers |64 eachcarrying a roller |65 are pivoted to the saddles i0 at |65, and are sopositioned that the rollers |65 are held in engagement with the cams |6|by springs |61 each of which has one end secured to a lever |64 and theother end secured to the adjacent cam |6 When a saddle is empty, thelever |64 pivoted thereto is held in engagement with a stop |68 on thesaddle I0, as illustrated in Fig. 8.

The saddles ||0 are revolved in a clockwise direction, as viewed fromthe near side of the machine as illustrated in Figs. l, 2 and 6, and areso positioned that they will operatively engage a keg Which is beingheld stationary on the rollers 90 and 9|, by the plunger 92. As thesaddle engages a keg, the nozzle |4 will enter the bung hole.

When a keg is received on a saddle H0, it will depress the lever |64which in turn, through the roller |65, depresses the cam |6|. The cam inturn, by its engagement with the roller |60, will depress the lever |51which will open the valve |52 by forcing the Valve stem |55 inwardly,and admit Water to the nozzle ||4 which sprays it over the interior ofthe keg. After the saddle has been rotated to the position shown in Fig.8, the roller will engage the notch |52, which Will allow the valve |52to be closed by the pressure of the water and the spring |53, thusstopping the flow of water to the nozzle |4. Continued movement of thesaddles will cause the roller |60 to ride out of the notch |62 and openthe valve |52, again admitting water to the nozzle ||4. The valve willthen stay open until the roller |60 rides off the end of the cam,sometime before the saddle deposits the keg on the discharge runway 1.The cam |6| may have one or more notches of varying lengths, and it willbe apparent from the foregoing that the design of the cam |6| determinesthe manner in which Water is admitted to the nozzle ||4.

The saddles I|0 are rotated continuously, rst one saddle and then theother receiving a keg from the bung locating mechanism. The machine asshown is so arranged and timed that a keg will stay in each of thevarious mechanisms, the length of time it takes to rotate the saddlesthrough 180.

The driving mechanism for the various parts Will now be described.

Power is supplied to the machine by rotating the shaft 39 through apulley |10 on one end thereof. The shaft 38 and rollers 36 are rotatedfrom the shaft 39, through a chain and sprocket connection indicated at|1|; and the shaft 25, and rollers 2|), are rotated through the frictionclutch 26, chain and sprocket connections |12 and |13 and idler shaft|14. An idler shaft |15 is rotated from the shaft 39 through a chain andsprocket connection |16. The shaft 93 is driven through the frictionclutch 91 and a chain and sprocket connection |11. A shaft |18,extending into the gear box |36 is driven from the idler shaft |15through bevel gears |19. A worm |86 is secured to the shaft |18, withinthe gear box |36, and meshes with a gear |8| keyed to the shaft |31. Aspur |82, keyed to the shaft |31, adjacent the gear |8|, drives a shaft|03 through a gear |84 keyed thereto. The shaft |83 has a cam |85 and acrank |86 fastened thereon. The operating lever 60 is oscillated by thecam |85 engaging a roller 80a on the lever |30. This in turn operatesthe lling nozzle 22, and brushes 4| at the proper time, as hereinbeforedescribed. The shaft I1, and from it the loading mechanism and thetransfer mechanisms 3a and 4a, is rocked by the crank arm |86, throughlink |31, lever |88, offset shaft |89, lever |90, link |6| and lever |92on the shaft |1.
